Ionic View slow to load app after upgrade to Ionic 3

[scottmotion]

Load time with Ionic View is significantly slower now. Get a blank screen for up to 30 seconds.
Any issues/solutions?

Post your package.json please so we can see what libraries you are using.
Did the load time also change in browser or when you build the app yourself?

I believe my issue is the same as:

Ionic 3 super slow with firebase on device/emulator

Hi, Did anyone try using firebase with Ionic 3 and testing on a device or emulator? It's taking forever to load.. I have angularfire ^2.0.0-beta.7-pre installed. It's weird because on browser it works good.. Any ideas? recommendation? PS. This problem didn't appear before I upgraded to Ionic3
